To all whom 'it may concern:

Be itknown that I, DAVID J. ANDREW, n citizen of the United States,residingat Lawrence, in the county of Middlesex and StateV ofMassachusetts, have invented certain new and useful Improvements inConcrete Buildings andMethods of Making lthe Same; and I do herebydeclare the following to be a full, clear, and exact description o f theinvention, such as will lenable others skilled in the art to 4which' itappertains to make and use the same.

The present invention relates'to concrete buildings and to an improvedmethod of r erecting such structures.

Prior to the present invention it has been proposed to erect what isknown in the art as a l reinforced concretel buildlngv by vconstructingtemporary wooden frames or molds 4 .for the various parts of suchbuildings which are to be made of concrete, and toprogressively, as thebuilding advances in height, deliver into such molds the concretemixture which surrounds and incloses the reinforcing metallic barsplaced in po-sition in said molds, and after the concrete mixture hasset suiiciently, the frames or molds are removed and this process isprogressively advanced until the reinforced concrete structure-hasattained itsdesired height. It has further beenl proposed to erect abuilding, suchv as dwelling house, in sucha manner as to produce whencompleted a monolithic concrete structure, and it has been suggestedthat this could be done by providing sui-table metal mold-s which couldbeset up' at" the location of Vthe proposed building and the concretemixture poured into such molds ina semi-'liquid -form and allowed to setwhile protected and inclosed `by the molds for a suliicient length oftime to harden, after which the molds 'are to bei removed, leaving thebuilding in a -practically complete state with; .the exception of thefinish. The first method has been found to bey objectionablek by reason'of itscomparatively slow and costly procedure, and by reason of thelarge `waste of material in both molds and struc- -ture, a large amountof material being em-l 'ployed'in't-he structure unrequired to sup-`port it or to resist the: elements. With regard to the second methodproposed of molding or casting a monolithic bu-ildingin its entirety,the cost of 'the molds renders the use of the method Aunadapted to anypurpose 'except the erection of a large number of houses or structuresof identical design. -There 1s a constantly increasing demand, however,for concrete' buildlngs and more is with the object of producing suchbuildlngs 'of individual design in an expeditious duced quantity ofmaterials of const-ruction, thatI-have produced-my present linventlon.

of'a concrete building and the method 'of after set forth and claimed.

The invention vfurther consistsof the im'- proved monolithic section orpanel for concrete buildingswhich will be hereinafter described andclaimed. l

My invention isillustrated in-the accompanyi'ng drawings in which:

dwelling housev embodying the same.- Fig. 2 is a section taken on line2, 2 of ig.' l; Fig. 3 isan enlz tr, ,'ed view ofthe central poron`line4, 4 of Fig. l.

In carrying out my invention I cast or mold of any suitable concretemixture the panels l' wliichniay be of any desiredsize,

or panels 1V will be of a size to form a considerable part ofthe wallsof the building 'to be erected, and as .shown .in lthe'drawing they areof a size to'extend entirely across the building from side to side' andlof a height corresponding to the height between the floors or Vstoriesof the building.

In the process of casting or molding, the anels 1 will be provided withsuitable open- -ings 2 for the windows and doors'. The sections orpanels 1v it lwill be understood are cast or, molded previous ,tobeginning the erect-ion ofthe building, and are allowed to removal fromthe molds andtheir handling the wall-of the building by means of a castor a molded monolithic frame or casing inof the sections or panels f1and comprises the sill 4, the belt course 5, and the cornice and plate 6extending` between and connecting the corner posts 8 and'9, whichframeis cast particularly forv concrete dwellings, and it manner, atsinallexpense,'and of greatly retion of Fig. 2, and Fig. 4 is a section taken`shape or thickness.:l Preferably the sections` set al suflicient lengthof time to permit their dicatedv in a general wayby thereferencecharacter, which as shown in Fig. 1 of the drawing, entirely surroundsthe outer edges eol To the above ends my invention consists iconstructing the same which will be herein- Figure 1 shows a frontelevation of a in the 'course of constructing the building, and they areheld in lace and supported in 'tureand they are strengthene or molded inposition in the house or build. ing and about the edges of thepreviously molded and erected sections or panels.

Briey thenmy' invent-ion may be said to consist of the employment ofpreviouslymolded sectionsor panels set in position in the wall of thebuilding and secured therein by a surrounding and inclosing supportingframe of concrete material cast or molded in place during theconstruction of the build?l 4 will be molded or castinfposition in thestructure and will be provided along its upper edge with arabbetedrecess into which the ylower edge of the lower sect-ion l willbe embedded.

The house wil-lconsist of the vpreviously cast or molded sectionsinclosed by the cast or molded 'retaining frame which when set formspractically a monolithic structure.

'The word anel as used in the claims is intended to eiine any form ofsection .of

whatever shape or design vadapted to be.

united-to other panels of the same or diiierent shape lby a castormolded frame.

The expression concrete, as herein employed,'is intended to include anyform of plastic material which is capable of bein@ cast or molded andthereafter becomes solid and strong.

Having thus described the invention what is claimed is l 1.Y rlhevmethod `of constructing the walls 'of concrete buildings which consistsin mold- .embraces the -upper e ing .or casting a suitable number ofconcrete panels and allowing them to harden, each of said panels beingof suitable width and of a height substantially' equal to the distancebetween the floors of the. building desired, ar-

ranging' a plurality 4of said panels in their nal position to inclosethe first floor, casting a sill at the base of said panels and castingvertical posts connecting ladjacent panels, then lacing a secondseriesof panels above sai yiirst floor panels, to inclose the secondfloor, casting a belt course around the adjacent edges of the first andsecond door panels and casting vertical posts connecting adjacent panelsof said lsecond floor course, continuing said operation until walls ofthe desired height are produced, then casting a cornice on the top edgesof the upper series of panels, saidl sill, vertical posts, belt coursesand cornice being so cast as to form a monolithic frame for said panels.

2. The method of constructing the walls of concrete buildings whichconsists in molding or casting a suitable number of concrete panels andallowing them to harden, each of said panels being of suitable width andof a height substantially equal to the distance loefx tween the floorsof the building desired, arranging a plurality of said panels in theirinalposition to inclose the first iioor, casting a sill at'the base ofsaid panels, casting vertical posts connecting adjacent panels, andcasting a belt course irder section which ges of said panels, saidsill,vertical posts and belt course girder section being'so cast as to form amonolithic frame which entirely surrounds each panel.
